Combustible paste



Patented Nov. 22, 1932 oar ALBEBiT A EPSTEIN, OF NE'W YGRK, N. Y., ASSIGNOR TO CONSOLIDATED PATENTEES CORPORATION, 0F NEVJ' YORK, N. 55., A CORPORATION OF NEW YORK COMBUSTIBLE PASTE N0 Drawing.

This invention relates to a combustible paste and also to. a process for its production and has for its primary object the preparation of .a paste having exceptional high burning characteristics and which may be ei'iectively merchandised in collapsible containers or air proof wrappers.

-An object of the invention is the preparation of a combustiblesubstance which will burn over an extended period witn a quiet, smokeless, non-sputtering flame.

Another object of the invention is the preparation of a combustible material which is non-explosive and incapable of spontaneous combustion and may be readily discharged from a container and burnt in this discharge position without possibility of igniting the material remaining within the container.

Another object of the invention is the production of a combustible paste that may be deposited in a burning position of any required volume and which will effectively produce the required volume of flame over an extended period without efiecting the general formation of the paste during the burning process.

A feature of my invention resides in amethod of producinga combustible paste by taking advantage of the insolubility of a combustible material when impregnated with a highly inflammable fluid such as alcohol.

Another feature of my invention resides in regulating the consistency of the combustible paste by varying the volume of alcohol with which a combustible substance is impregnated.

Besides the above my invention is distingu'shed in the combination of a combustible substance with an inflammable fluid, and an ingredient that will absolutely control the characteristics of the flame produced during the burning process.

l/Vith this and other objects in view the invention willbebetter understood from the following detailed description of one embodiment of my invention.

My invention is based upon the principle that alcohol (methyl, ethyl or denatured) forms a cream or paste with certain insoluble combustible materials, such as magnesium Application filed Hevemher 13, 1930. Serial No. 495,538.

stearate. tial solution of the magnesium stearate in alcohol, in consequence of which a material of past-y and cohesive consistency is obtained, e nbod ing' a-high amount of a very combustible'fluid (alcohol) which enables the paste to burn with a large volume of flame over an extended period.

Of course, it is to be understood that other combustible materials maybe substituted for magesium stearate such as various grades of fats, tallow and fatty acids to which is added a chemical to render the same practically insoluble. i

With this material is mixed a highly in flammable fluid such as alcohol, as above set forth, the volume of alcohol in relation to the mass of the combustible material determining the consistency o; the paste, thereby enabling the paste to be usable for a multiplicity of purposes in the commercialization thereof.

Example one A suitable type of paste can be produced by mixing one part of a combustible material (such as magnesium stearate) by Weight, with two parts alcohol, by volume, stirring the mixture until a homogeneous mass is obtained.

Example two A suitable type of fat or fatty acid may be mixd with a metallic salt and a predetermined quantity of the mixture placed within a predetermined volume of alcohol and subject to agitation.

Due to the insolubility of thematerial and the chemical reaction between the salt and the fatty substance, the alcohol only partially dissolves the material, the remaining portion O'i the alcohol being held in suspension by its mechanical mixture, with material.

For th purpose of modifying the character of the flame produced during the burning of the paste, various ingredients may be placed in the mixture each having anindividual reaction upon the character andthe color of the flame produced. .As an example of such compounds, I cite the following "exampl'es:

The reaction involved is the par- Example I three To a predetermined quantity of combustible paste, produced as outlined above, I mix a small quantity of a soluble wood distillate, such as turpentine.

Example four E mample five To a predetermined quantity of the combustible paste, produced as above set forth, I add an insoluble solid such as finely powdered charcoal or other forms of carbon.

'Of-course, it is to be understood that various other ingredients may be added for modifying'the character of the flame produced. Due to the addition of the substances just set forth, the color of theflame ranges between blue and white, the alcohol in the compounc cooperating in the production of a flame that is smokeless. I have found from actual experience that the character and color of the residue, after a burning operation, may be controlled by the type of ingredient placed in the combustible paste outlined above. I have also found from actual experience that when charcoal, lampblack or similar ingredicuts are added the combustion is considerably prolongedand a glowing residue of the caronac-eous material remains until the combustion is complete;

In the production of the compound set forth in Example 3, I find excellent results can be accomplished by mixing 9 parts of alcohol with one part of turpentine, stirring the solution until complete miscibility of the turpentine and alcohol is obtained. To this mixture, I add, during a constant stirring operation, 5 parts, by weight,of the combustible material set forth above, such as magnesium stearate.

In carrying out my method for production of the compound set forth in Example 4, I take two parts of rosin or camphor and add the same to parts of alcohol to which turpentine has been added, then adding to this mixture 50 parts of a combustible material, as set forth above, subjecting the same to constant agitation.

In the production of the compound as set forth in Example .5, I take 100 parts of an alcohol-turpentine mixture, as produced in carrying out the method involved, in Example 3 and mix this with 17 parts of a combustible material, such as magnesium stearate. To this is added 33 parts of finely powdered charcoal constantly agitating the mixture during the production of the compound.

AlthoughI have only set forth a few of the many types of products that maybe produced, I wish it to be understood that many more can be produced in the use of my basic principles, one of the basic principles residing in the impregnating of a combustible material with alcohol to produce a paste that may be directlyburnt at the point of dis-.;

charge and which will burn in a smokeless manner leaving aresiduethat may be readvolved in the carrying out of-my basic principles I do not wish to be limited in protection in any manner, whatsoever, except as set forth in the following claims:

What I claim is:

1. A combustible paste comprising a ture of one part of ma-gnesium-stearate by weight with two parts of 'alcoholby volume J and a flame modifying ingredient added thereto. 7 4 2. A combustible paste consisting of magnesium stearate, a volume of alcohol, a quan+ tity of turpentine and finely powdered charcoal.

8. A combustible paste comprising 100 parts of a mixture of alcohol and turpentine, 17 parts ofmagnesium stearate and 33 parts of finely powdered charcoal.
